Paul J. Kinzel, Jonathan M. Nelson, Gregory W. Kennedy, David H. Bennion
2016, Conference Paper, Proceedings of River Flow 2016
The introduction of rock-rubble substrate in rivers, to enhance fish spawning habitat, represents a significant investment in planning, permitting and construction. Where river processes deposit sediment and cover the substrate, its value as fish spawning habitat can be diminished. Therefore, it is crucial in the site se-lection process, that substrate...

2016, Journal of Geophysical Research: Biogeosciences (121) 2960-2975
High-latitude ecosystems are experiencing the most rapid climate changes globally, and in many areas these changes are concurrent with shifts in patterns of herbivory. Individually, climate and herbivory are known to influence biosphere-atmosphere greenhouse gas (GHG) exchange; however, the interactive effects of climate and herbivory in driving GHG...
White-tailed deer (Odocoileus virginianus) subsidize gray wolves (Canis lupus) during a moose (Alces americanus) decline: A case of apparent competition?
Shannon Barber-Meyer, L. David Mech
2016, Canadian Field-Naturalist (130) 308-314
Moose (Alces americanus) in northeastern Minnesota have declined by 55% since 2006. Although the cause is unresolved, some studies have suggested that Gray Wolves (Canis lupus) contributed to the decline. After the Moose decline, wolves could either decline or switch prey. To determine which occurred in our study area, we...

Henry M. Streby, Sean M. Peterson, David E. Andersen
2016, Book chapter, Golden-winged Warbler ecology, conservation, and habitat management (Studies in Avian Biology, volume 49)
Postfledging habitat use and fledgling survival remain unstudied for most songbirds, but this period is critical for understanding breeding habitat associations and full-season productivity. We used radiotelemetry to study movements, cover-type selection, and survival of fledgling Golden-winged Warblers (Vermivora chrysoptera) during the dependent postfledging period in managed forest landscapes of...
Weather as a proximate explanation for fission–fusion dynamics in female northern long-eared bats
Krista J. Patriquin, Marty L. Leonard, Hugh G. Broders, W. Mark Ford, Eric R. Britzke, Alexander Silvis
2016, Animal Behaviour (122) 47-57
Fission–fusion dynamics appear common among temperate bats where females form roost groups that change in size and composition, as females switch roosts almost daily. One hypothesis for frequent roost switching is that females move to find suitable thermal conditions as ambient conditions change. Tests of this hypothesis have, however, been...

Kelsie Murchy, Brooke J. Vetter, Marybeth K. Brey, Jon Amberg, Mark P. Gaikowski, Allen F. Mensinger
2016, Proceedings of Meetings on Acoustics (27) 1-9
Bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix) (hereafter: bigheaded carps), and common carp (Cyprinus carpio) are invasive fish causing negative impacts throughout their North American range. To control their movements, non-physical barriers are being developed. Broadband sound (0.06 to 10 kHz) has shown potential as an acoustic deterrent for...
Updated atomic weights: Time to review our table
Tyler B. Coplen, Fabienne Meyers, Norman E. Holden
2016, ChemistryViews Magazine (05 April 2016)
Despite common belief, atomic weights are not necessarily constants of nature. Scientists’ ability to measure these values is regularly improving, so one would expect that the accuracy of these values should be improving with time. It is the task of the IUPAC (International Union of Pure and Applied Chemistry) Commission...
